Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for receiving data transmitted in discrete data increments, wherein the data increments are transmitted via a first channel, and detection parameters for the data increments are transmitted via a second channel, the detection parameters including parameters related to packet length for the transmitted data increments, a ratio of data channel to pilot channel transmission power, and a sequence indicia for the transmitted data increments, the method comprising the steps of: transmitting via the second channel the packet length and transmission-power ratio parameters corresponding to data increments transmitted on the first channel, wherein the sequence-indicia parameter corresponding to the transmitted data increments is not transmitted; detecting ones of received data increments in accordance with values of received corresponding packet-length and transmission-power-ratio parameters and different assumed possible values of the non-transmitted sequence-indicia parameter; determining for each different combination of received packet-length and transmission-power-ratio parameters and assumed sequence-indicia parameter value if the data detected in accordance with that assumed parameter value passes a CRC check; and if the data detected in accordance with an assumed sequence-indicia parameter value passes the CRC check, delivering that detected data to an output.
2. The method of claim 1 wherein the at least one parameter is a plurality of different parameters each having a plurality of possible discrete values, and the step of detecting the received data in accordance with different assumed possible parameter values is performed over at least some of the combinations of possible discrete values for each of the parameters.
